WATER-CLOSET CONNECTION.

Specification of Letters Patent.

Patented June 11, 1912.

Application filed August 28, 1911. Serial No. 6463314.

To all whom tt may cancer n Be it known that I, J OSEPI-I J. Cosenovn, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in VVater-Closet Connections, of which the following s a specification, reference being had therein to the accompanying drawing.

This invention has relation to certain improvements in the type of water closet con nections, shown and described in U. S. Letters Patent granted to me July 5th, 1910, and has for its object the provsion of novel means for connecting a water-closet or similar article which rests on the floor, with the soil pipe, so as to avoid the breaking of the soil pipe or of the floor fiange of the closet or the floor fiange of the connection or any other damage to the closet or its connections by the Settlement of the soil pipe or the sinking or sagging of the floor.

The invention disclosed in my said patent consists in providing a flexible floor plate or flange which has a seat, to receive the collar surrounding the closet outlet, the flexibility of the floor flange being obtained by interposing a metallic ring, preferably corrugated in concentric circles, between a rigid ring resting on the floor and the soil pipe, which corrugated ring will support the soil pipe in proper alinement with the closet outlet and yield under strain so as to allow of any required fleXure of the soil pipe or impairment of the synmetry of connected parts without breaking the connections or inducng leakage.

By Iny present improvement I substitute for the corrugated disk of my patent and the cast metal floor flange to which the disk is attached, a single piece, forming both floor plate and flange, in the form of a orimped or corrugated ferrule, which is made of thin stamped or pressed netal and which is soldered at its lower inturned edge to the soil pipe, and, rising therefrom, is cup shaped at its upper part, to receive the ring which is attached to the outlet fiange of the earthenware closet, thus forming a sleeve-joint connection between the closet and the ferrule, such sleeve-joint being a joint of the spigot and faucet type the members fitting one within the other without being threaded or otherwise formed With inter-looking means.

In the accompanying drawings illustrating my invention as applied to an earthenware water-closet and its soil pipe Figure 1 is a vertical sectional view of a portion of a water-closet and a portion of a vertically arranged soil pipe with my improved connection applied thereto. Fig. 2 is a horizontal section on the line w-c of Fig. 1 looking downward.

The bowl or closet, designated l, is of the usual or any desired type and is formed with the outlet passage 2, terminating in a flange or projection 3, which is threaded on the outside as shown at t, to receive a collar 5, which latter is slightly tapered inwardly toward its lower end, so as to rest in a correspondingly tapered or conical seat formed in a ferrule 7.

The ferrule 7, constructed according to my present improvement, is a separate structure from the soil pipe 8, which is in the usual 'form of a section of lead tubing of an interior diameter corresponding to the diameter of the outlet passage of the closet, and said ferrule is corrugated or crinped to impart to it the required flexibility. The lower edge of the ferrule 7, is secured to the soil pipe by soldering as at 9.

In fitting the soil pipe and other parts to their proper position with relation to the closet, the soil pipe is passed through the floor opening to about the level of' the floor line and the corrugated ferrule 7 is then slipped over the end of the pipe and its edges soldered to the pipe. The closet bowl, carrying the collar 5, is now placed in positon, with the collar 5 resting in the tapered mouth lO of the ferrule, and the bolts 10', which pass upward through holes 12 in the closet base and through the lugs 12', are tghtened up by means of the nuts 13.

The lugs 12 are strips of stamped or pressed metal, preferably galvanized steel, having, at their inner ends, upturned flanges 14, which engage with and under the outwardly and downwardly bent or curved fiange 15, formed on the upper edge of the flexible connection 7, and are turned upwardly at their ends as shown at 16, to rest against the under side of the closet base. The upturned ends 16 of the lugs 12 are rounded and the heads of the bolts are also rounded as shown, so that they will adapt themselves to any irregularities in the setting of the closet. When the lugs 12 are first placed in position, and therefore the closet is set in place, the bolts are inserted from below the lugs, and the latter being fitted to the ferrule, paper or other soft filling, is packed or wedged under the flange and bolts so as to hold them temporarily in position with the bolts upright. The closet being then lowered the bolts will pass through the vertical bolt holes in the closet without disturbing the lugs, after which the washers and nuts are put on the bolts and the latter tightened up.

The collar 5, insteadof being threaded on its interior to screw on the flange 3, is preferably for-med with indentations at intervals corresponding to the pitch of the screw thread on the closet flange, so as to engage with and be screwed on the flange 3, but other methods of securing the parts together may be used, such as a bayonet joint arrangement. i

As will be seen none of the weight of the closet is supported by the soil pipe, nor is any part of the closet connections brought into such contact with or relation to the soil pipe as to at'fect or to be aflected by any change in the position of'the soil pipe with reference to its alinement with the closet outlet opening. Any unevenness in the floor or abnormal condition or relation of the soil pipe to the closet is compensated for by the flexible corrugated ring, which yields under slight strain without breaking or rupturing the parts connected thereto or opening up any seams or subjecting the parts forming the closet connections to the soil pipe to strain or other injurous effects.

The application of the corrugated flexible ring embodies the novel desideratun of a metal-to-netal flexible connection between the closet and soil pipe, which will enable the closet, soil pipe and joint elements to be installed and maintained in satisfaotory relation and insures a water tight joint under the varying conditions which are encountered in the first installation of the closet and after lapse of time.

Having described my invention, I claim and desire to. secure by Letters Patentl. The combination with the soil pipe of a water-closet, of a flexible floor plate and flexible flange, constituting a ferrule, attached to the soil pipe and embracing the outlet flange of the closet and forming a sleeve joint connection therewith.

2. The oombination with the soil pipe of a water-closet, of a combined floor plate and flange, said flange being flexible and adapted to form a sleeve joint connection with the closet.

3. The combination with a water-closet, a tapered ring surrounding the outlet flange of the closet, and a soil pipe, of a combined floor plate and flange, which is connected to the soil pipe, and tapered to receive said ring, said flange being fleXible and forming a sleeve joint connection with the closet.

4. The combination with a soil pipe of a combined floor plate and unthreaded flexible metallic corrugated flange made of a single section of metal pressed to shape and secured to the soil pipe and forming a sleevejoint connection with the closet.

5. The combination with a water-closet having a tapered metallic ring surrounding its outlet opening, of a soil pipe and a fleXible integral floor plate, and flange secured to the soil pipe and having a tapered seat to receive the tapered ring of the closet.

6. The combination with a water-closet and soil pipe, of a combined floor plate and flexible flange, forming a connection between the closet and soil pipe, and consisting of a single piece of pressed metal of tubular, cylindrically corrugated form in rigid connection with the soil pipe.

In testimony whereof I affiX my signature in presence of two witnesses.
